The mulch biomass was composed of spontaneous plants of various local species: malva roxa (Urena lobata L.), "capim estrela" (Rynchospora speciosa), "lingua de vaca" (Symphytum officinale L.), "joa" (Solanum viarum), "trapoeraba" (Commelina benghalensis L.), grass (Paspalum notatum), "quebra pedra" (Phyllanthus niruri), "betonica" (Stachys officinalis), "serralha mirim" (Emilia sonchifolia L.), "carrapicho" (Cenchrus echinatus L.), "lombrigueira" (Spigelia anthelmia L.), "tiririca" (Cyperus rotundus L.), "caruru" (Amaranthus viridis), "amendoim bravo" (Euphorbia heterophylla L.), "barba de bode" (Eragrostis curvula), "picao branco" (Galinsoga parviflora), being Brachiaria brizantha the most abundant species, accounting for 90% of the biomass.
The six most frequent weed species made up 92.13% of all weeds before electro-shock treatment; they were all dicotyledons, except for wheat volunteers; their percentage control levels in Table 4 were: gallant soldier (Galinsoga parviflora), 98.2%; wheat, 97.1%; smooth sow thistle (Sonchus oleraceus), 100%; common mallow (Malva sylvestris), 100%; milkweed (Euphorbia heterophylla), 94.5%; and spurge Chamaesyce hirta, 74.8%.
Major weed species observed in the winter were Galinsoga parviflora, Lamium amplexicaule, Conyza canadensis, Lactuca serriola, Senecio vulgaris and Crepis runcinata.
